Overview
The Dodge 111023 taper-lock sheave is a precision-engineered 4-groove pulley for industrial V-belt drive systems. This Type A1 sheave accommodates 5V cross-section belts and features a taper-lock bore design that accepts the included 2517 bushing, enabling shaft bore adaptation from 1/2″ to 2-11/16″. Manufactured in Dodge plants under ISO 9002 quality standards, the 111023 delivers smooth, efficient power transmission with minimal maintenance requirements.
Key Features

Replaces / Drop-In Replacement For
The Dodge 111023 is a direct replacement for OEM Dodge 4/5V8.5-2517 applications where Type A1 taper-lock sheaves with 4 grooves and 8.5″ OD are specified. Similar-sized models in the Dodge line include the 111022 (8.0″ OD, 7.9″ pitch) and 111021 (7.5″ OD, 7.4″ pitch), though these are not direct drop-in replacements due to differing pitch diameters.
Works With
- Taper-lock bushing 2517 (required for installation)
- 5V belt section compatibility for power transmission efficiency
- Standard industrial mounting and alignment practices
- Both fixed and variable speed drive systems (within 6500 FPM rim speed limit)
